Chromosome analysis in operating room personnel.

Area of Science:

• Occupational Health
• Cytogenetics
• Environmental Medicine

Background:

• Operating room personnel may be exposed to anesthetic gases and ionizing radiation.
• Potential genotoxic effects of occupational exposures in healthcare settings require investigation.

Purpose of the Study:

• To assess cytogenetic damage, specifically chromosomal aberrations and sister-chromatid exchanges, in hospital workers exposed to anesthetic gases and ionizing radiation.
• To determine if exposure to anesthetic gases alone or in combination with ionizing radiation causes significant chromosome damage.

Main Methods:

• Cytogenetic analysis (sister-chromatid exchanges and chromosomal aberrations) of blood samples from 45 hospital workers.
• Categorization of workers into three groups: anesthetic gases exposure, anesthetic gases and ionizing radiation exposure, and controls.
• Statistical analysis to compare cytogenetic damage between groups and correlate with employment duration and smoking habits.

Main Results:

• A statistically significant increase in chromosomal aberrations was observed in all exposed personnel compared to controls (P = 0.029).
• No significant difference in sister-chromatid exchanges was found between exposed and control groups.
• Chromosomal aberrations showed a positive correlation with years of employment in exposed staff.
• Higher, though not statistically significant, levels of both sister-chromatid exchange and chromosomal aberrations were noted in smokers.

Conclusions:

• Combined exposure to anesthetic gases and ionizing radiation in operating rooms is associated with increased chromosomal aberrations.
• Occupational exposure to anesthetic gases and ionizing radiation poses a genotoxic risk to operating room personnel.
• Long-term employment in these environments may increase the risk of cytogenetic damage.
